Flake graphite is used as a functional filler for coatings, mainly for anti-corrosion coatings, fireproof coatings and conductive coatings. As an anti-corrosion material, it is an anti-rust primer made of carbon black, talc and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the anti-rust effect will be better.

Among the lithium-ion battery materials, the anode material is the key to determine the battery performance. As a graphite material with high crystallinity, the particle size of flake graphite directly affects the specific surface area of the electrode and the proportion of carbon atoms at the edge, which has a great influence on the irreversible specific capacity during electricity, so flake graphite plays a vital role in the battery.

Flake graphite is one of the important materials for lithium batteries because of its high electronic conductivity, large lithium ion diffusion coefficient, high intercalation capacity and low intercalation potential. The flake graphite can stabilize the voltage of the lithium battery, reduce the internal resistance of the lithium battery, and make the storage time of the battery longer. Increase the battery life. Flake graphite can reduce the amount of flake graphite powder in lithium batteries and greatly reduce the cost of batteries. Flake graphite is natural crystal graphite, its shape is like fish phosphorus, is a hexagonal crystal system, a layered structure, with good high temperature resistance, electrical conductivity, thermal conductivity, lubrication, plasticity and acid and alkali resistance and other properties. Flake graphite is a kind of solid lubricant with layered structure, which is rich in resources and cheap.

The flake graphite material has the characteristics of high temperature resistance, chemical corrosion resistance and good conductivity, so both positive and negative plates can be used to enhance the conductivity of the plates and improve the utilization rate of active research materials. The addition of graphite also increases the porosity and liquid absorption of a polar plate, which can provide a higher discharge environmental capacity at low temperatures by improving the discharge technical performance of the polar plate, and can prevent the agglomeration and shrinkage of the active research material. What are the characteristics of flake graphite? Let's take a brief look at it.

1. High-purity graphite uses flake graphite as raw material, adopts advanced production technology, has higher purity and low impurity content.

2. Highly dispersed, uniform particle size.

3. Significantly improve the initial capacity and high current discharge performance of the battery.

4. Battery charge acceptance.

In order to better apply flake graphite, first of all, we need to understand the advantages of flake graphite.

1, in use, the manufacture of crucible and expanded graphite need to use large-scale graphite, fine specifications can not be used or difficult to use; in the preparation of graphene raw materials, large-scale graphite is more conducive to the formation of graphene.

2. Flake graphite is relatively small in the overall output of graphite. In addition to extraction from raw ore, modern industrial technology cannot produce synthetic large flake graphite. Once the flake is destroyed, it cannot be restored, while fine flake graphite can be obtained by crushing large flake graphite.

3. Flake graphite is superior to small flake graphite in terms of lubrication performance. The larger the flake graphite, the lower the friction coefficient and the better the lubrication performance.

4, flake graphite in the economic and social value, the same cultural taste, large flake graphite price is dozens of times the fine flake.

5, from the reserves point of view, China's large flake graphite reserves are low, in the process of selection due to the complex re-grinding process resulting in serious damage to the graphite flake, less output, resulting in a market in short supply.
